2017 Lincoln Mkc

Check Engine Light present. Took car to Ford dealership. Formal diagnosis from Ford dealership: Coolant intrusion present causing misfires, specifically in cylinder 4. P0304 and P0316 codes present. This is a known manufacturing issue; however, Lincoln customer service refuses to acknowledge the problem even exists. Upon talking to the Ford dealership service members, they stated that this is a common issue. One of the service members stated he has already dealt with multiple vehicles with this exact problem this week alone. Having an engine (misfire, steam, etc) go out due to a manufacturing/design flaw, especially while driving on the highway, is a major safety issue. Service team instructed me to no longer drive vehicle which would cause catastrophic damage.

I am filing a formal safety complaint regarding my 2017 Lincoln MKC equipped with the 2.0L EcoBoost engine (VIN: [XXX]). The vehicle has experienced a severe, progressive engine failure caused by internal coolant intrusion into Cylinder 1, directly matching the structural design defect detailed by the manufacturer in Technical Service Bulletin TSB 22-2229. This defect allows pressurized engine coolant to continuously leak directly into the combustion cylinders while driving and during engine rest. This creates an immediate safety risk of vehicle hydro-locking during ignition, sudden mid-drive engine stalls at highway speeds due to severe misfires (Fault Code P0301), and unexpected engine overheating. The manufacturer has knowingly built these open-deck engine blocks with narrow coolant grooves prone to fracturing, creating an ongoing risk of sudden thermal failure and power loss in active traffic. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

About 3 weeks ago, I was driving, and a red flashing light came on, signalling that my coolant was low. I bought radiator fluid and put it in up to the fill line. I visited my daughter, which is 11/2 hr. away. I checked the radiator reserve when I arrived at her house. The reserve was empty again. I brought it to a local mechanic shop. They diagnosed that I have coolant intrusion in the engine. They said I would need to pay for a new engine around $8800-$9200. I had purchased a lifetime extended warranty when I purchased the car. The Ford dealership diagnosed my car with the same problem as the local mechanic. They said the repair was not covered by the Powertrain warranty do to it being a manufacturing failure. I brought the car home and it has been parked since.

Lincoln MKC 2017 Engine failure due to Coolant leak. Bought new Lincoln MKC 2017. The current mileage is 52, 500. Upon Starting, engine would shake for about 10 seconds. The Engine light would come ON. Engine light would turn OFF and ON for few weeks. The Dealership diagnostic indicated code P0301. I was advised Full Engine replacement. Currently the Engine is not starting at all. I have heard it's a design issue with the Engine. I have contacted multiple Lincoln dealerships, and each one has its own engine replacement costs. Lincoln Concierge declined my request to help in anyway although it seems to be a design issue with the Engine.

I took my vehicle to the local Ford dealership for service due to a check engine light being on. They pulled the spark plug and found the cylinder full of coolant and found TSB-22-2229. I called Lincoln and was told they wouldn’t assist me because I fell outside their time and mileage limits. This issue should have been a recall due to their defective engine design. Engine replacement is very costly and the company should take responsibility for this flaw.
